Foxtail?

There is nothing wrong with the plant what i see. Some strains tend to foxtail more then others nothing to worry about! Start the flush to get rid of all excess nutes in ur medium and leaves and harvest in 10/14 days then dry it for 10/14 days and you will have some really really amazing smoke!

Saltivas tend to foxtail more and some strains are bread to fox tai lif that's what you're wondering, like if one of the seeds has that characteristic and it states it or something. and other times some strains just have more of a pointy shape., like my Nevilles haze kind of looked like it was fox tailing at first .but as the upward bud growth kept going the bud growth below filled out and evenly made fat tall colas. That 16 week flower strain. You could have quite a few more weeks left if its got a lot of sativa. Although some strains don't, for the most part the green/white hairs will all be orange but only a few, and mostly notice it on the top nearest the light. Honestly, you don't exactly want to follow how long it says to flower and any seed packet anyway that's just a guideline. Two seeds even in the same well-stabilized line could vary in optimal flower time by a week or even 3. and unless you are breeding it doesn't really matter what plants they are as long as you like them,and can distinguish them somehow. just make sure to label them in some way when you do harvest at past plant 1-2-3 and you can test them, and if giving away friends as medicine you can label what you think its effects are bc i don't believe that some people can only smoke Indica or sativa think it ultimately depends on a plant to plant basis. so good to test effects regardless of what you think it is, and have a subjective opinion.

It looks at that bad tbh, try adding some silica to your nut solution
